SANDICOR / SDMLS over 28,000 listings' photos updated

Hi, I noticed there are lots of image updates to grab and wanted to see if there was something unusual going on.

We started a download at 12:46pm PST and there were updates for 28,197 listings. That finished at 4:54pm and then we checked for updates again...there were image updates for 29,611 listings this time, all of which were dated beyond the download we just finished. We can't really keep up with this so I wanted to check if there were any known issues. Thanks!
